Laminin staining of TA muscle cryosections at 30 dpi in DMD mice showed that around 341 fibers were contributed by GFP+tdT+ (Gli1+) MuSCs during the regeneration process, whereas GFP-tdT+ (Gli1−) MuSCs contributed to approximately 108 fibers (Fig. 6g, h). The gene discussed is GLI1; the disease is Duchenne muscular dystrophy.
